[0017] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0018] A harmonica with reeds that can be easily disassembled and replaced, such as Figure 1-Figure 3As shown, it includes a piano frame 1, a lower spring plate 2, an upper spring plate 3, a cover plate 4, a seat plate 5, a telescopic rod 6, a spring 7, a gasket 8, a fixing rod 9, a rotating plate 10 and a protrusion 11. The upper spring plate 3 is placed on the upper side of the piano frame 1. The left and right parts of the piano frame 1 are connected to upper and lower telescopic rods 6. The cover plate 4 is connected between the telescopic ends of the two telescopic rods 6 on the upper side. The cover plate 4 is made of metal and provides good durability and sound quality. The seat plate 5 is connected between the telescopic ends of the two telescopic rods 6 on the lower side. A lower spring plate 2 is placed on the side, and the lower spring plate 2 is in contact with the piano frame 1. Both the lower spring plate 2 and the upper spring plate 3 are provided with sliding grooves on the left and right parts, and the sliding grooves are in contact with the telescopic ends of the adjacent telescopic rods 6, so as to facilitate the removal of the lower spring plate 2 and the upper spring plate 3. Gaskets 8 are slidably connected to the telescopic rods 6, and springs 7 are connected between the gaskets 8 and the piano frame 1. Two left and right fixed rods 9 are connected to the rear part of the piano frame 1, and the upper and lower parts of the fixed rods 9 are rotatably connected to a rotating plate 10, and the outer sides of the rotating plate 10 are connected to bumps 11.
